M1.9 flare occurred 11:20 on Dec 28, developed gradually to its EUV peak emission around 13:30 (GOES 1-8 /AA/ peak at 12:45, see http://www.lmsal.com/solarsoft/latest_events_archive/events_summary/2015/12/28/gev_20151228_1120/index.html). A coronal EUV wave was associated with the flare. Recurrent surges continue to originate from the leading sunspot of this AR (since a few days ago).

Recurrent surges from the same leading polarity of AR 12473 continued for another day.

A large polar coronal hole occupied almost 1/2 of the visible northern hemisphere, with two branches extending to lower latitudes near active regions. Note data gaps in the movie.

coronal rain and horizontal prominence threads along large-scale, trans-equatorial loops. At some moments, e..g, Dec 26 18:40 UT, there appears a shallow dip in the otherwise very flat loops. Cool 304 \\AA\\ material is concentrated near that dip.

Recurrent surges from the leading sunspot/pole of AR 12473 over the course of 20 hours or so. This sunspot exhibited continuous flux emergence, accompanied by flaring activities.

The eruption was probably triggered at high altitudes - no tracer like a filament/prominence was easily recognized. This must have been a big CME, but not super-energetic, considering no proton increase even though it originated in a region generally thought to be well-connected.

A minor eruption in AR 12488 evacuated the corona toward west. No CME was clearly associated.

This was a minor eruption with only a small region in the corona was seen to dim. Small post-flare loops formed on the limb.

2016-01-25T09:20:22 --> 2016-01-25T13:30:22
The corona over the limb is seen to erupt and dim. No clear filament eruption was seen, so it first appeared that this was a backside event. However, the formation of two-ribbon flare brightening (on which post-flare loops stood) shows that the eruption started on the visible side.

First, a prominence was ejected nearly horizontally (counterclockwise) from a low-latitude region near the west limb, which seemed to destabilize another high-latitude prominence, which eventually erupted. Then there was an opning of the coronal near the region where the first prominence eruption was triggered. But this probably represented activity behind the limb, and was not related to the prominence eruptions mentioned above.

The prominence was split into two parts, going up and coming down. The part that went up had a hotter front edge as seen in 171 A images. No associated CME was seen in LASCO data.

A flux rope-like structure is seen to move upward slowly, most notably in 171 A images. The prominence in 304 A images does not seem to erupt, but its higher-temperature counterpart does. This is an event that can easily escape our attention. There is hardly presence in coronagraph data.

We finally saw the spectacular eruption of the filament whose northwestern end was close to AR 12487. Although turbulent motions were occasionally seen prior to the eruption, no systematic upward motions were seen in images. Perhaps spectroscopic observations might have predicted the eruption in advance. The eruption itself was primarily toward southwest, so its potential to affect the geo-space may be limited.

The filament activation observed around 11:30 UT. However, the eruption failed with most of the filament material inatact.

A filament eruption observed at the SE limb. THe filament-cavity system can be seen before the eruption. The brightenings around the filament material during eruption are evident, which may indicate plasma heating involved.

A QS filament erupted near the NW limb. The eruption leads to loop brightings at the south of the filament. The reconnection may occur between the erupting field and the ambient field.
